Jeffrey Schneider, the senior vice president of communications at ABC News, was suspended this month after shouting at a staffer.

The incident, which Schneider confirmed, resulted in a two-week suspension that ended Monday. Schneider, who is widely known as a high-intensity figure at ABC and throughout the industry, was seen raising his voice in frustration at a staff member earlier this month.

Reached by phone, a contrite Schneider said he had been "out of line."

"I definitely lost my temper," Schneider said. "I was out of line. I made amends to the person involved, and I think the punishment was fair."

The suspension, which was first reported by Radar Online, resulted in Schneider being out of the office when ABC announced that Diane Sawyer would step down as anchor of "World News" and be replaced by David Muir. George Stephanopoulos, the "Good Morning America" and "This Week" host, will become the network's chief anchor.

Schneider's absence became a subject of discussion within ABC after a security guard accidentally posted Schneider's picture on the wall, network sources said. Security guards are regularly given photos of staffers who have been suspended to ensure they do not enter the building, but those photographs are meant to be kept in a binder, not posted for public viewing.

Schneider's two-week suspension is now over. He returned to work on Monday.
